A train goes at a constant speed. If it covers 150 miles in 2 1/2 hours What distance would it cover in 3 hours?
Hoochie [10]

Hi there!

In order to find your answer, you'll need to use the cross product method :

150 miles → 2 1/2 hours = 150 minutes

x miles     → 3 hours = 180 minutes

(150 × 180) ÷ 150 = x miles

27,000 ÷ 150 = x miles

180 = x miles


Your answer is: A train would cover 180 miles in 3 hours.


There you go! I really hope this helped, if there's anything just let me know! :)

What is 3/5 by 1/2 reduced?
Readme [11.4K]

Answer: 1/10

Step-by-step explanation:

I think you mean 3/5 - 1/2?

we need to make the denominators the same, so we find the LCM of 5 and 2, which is 1, so we multiply them to get a common denominator of 10.

Now we multiply 3/5 by 2/2 to get 6/10, and 1/2 by 5/5 to get 5/10.

6/10 - 5/10 = 1/10
